(1) | The financial information for the first three quarters of 2011 have been restated from amounts previously reported in the Company's quarterly reports on Form 10-Q for cost of product revenue, gross profit, loss from operations, total non-operating income (expense), net, and net loss. The adjustments made related to capitalized inventory costs, which should have been charged to cost of product revenue as products were sold. The Company has determined that although the corrections were immaterial to each of the quarters ended March 31, June 30, and September 30, 2011, the Company has decided to restate the amounts previously reported to better reflect the actual operating trends of the business for 2011. The adjustments primarily impacted the cost of product revenue by $0.1 million for each of the three months ended March 31, 2011, June 30, 2011 and September 30, 2011. In addition, there was no impact to loss per share as a result of these immaterial misstatements in each of the three months ended March 31, 2011, June 30, 2011 and September 30, 2011.
